1. Choice D

2. Choice C

Step-by-step explanation:

1. Let P(n) be the amount of money Pam had in her account at the end of n-th month. If Pam deposits enough money to double the amount currently in her account and immediately after her deposit she withdraws $100 from the account, then

You can rewrite this expression as

Given that January is the first month, April is the fourth month.

If Pam had $500 left in her account at the end of April, then

If Pam had $300 left in her account at the end of March, then

If Pam had $200 left in her account at the end of February, then

This means Pam had $150 at the end of January.
